Septal Flutter due to previous transseptal access What is interpretation of the following 3D maps acquired at the start of the procedure? An Advisor HD Grid (Abbott Laboratories Abbott Park, IL) was inserted to create an impedance-based geometry, a Local Activation Timing map, and a voltage map simultaneously. The atrial cycle length was consistently measured at a rate of 260ms.Via femoral venous access, a transeptal puncture was made to access the left atrium. On the procedure date, the patient presented in this atypical flutter, which exhibited a varying 3:1P:QRSratio. Pharmacologically treated following the initial ablation, the patient opted for a second ablation to cure this atypical flutter. ![]() Upon follow-up, the patient presented to clinic in a 12-lead interpreted flutter. The additional RF energy did not terminate this atypical flutter, and a DCCV was administered to restore sinus rhythm, prior to the completion of the case. In hopes of terminating the atypical flutter, the operator performed two additional lines of ablation in the left atrium a mitral isthmus line and an anterior wall line. Following the completion of the PVI, an eccentric CS-activated flutter arose. This 77-year-old male, with a history of Paroxysmal Atrial Fibrillation, received a Pulmonary Vein Isolation ablation, in May 2019.The electrophysiology operator used a cryo balloon (Freezor Medtronic, MN)to perform the PVI in 2019.
